I can see no reason why it should not be possible to have several lists, one of dogs that are banned and a second of dogs that should always be on a lead and muzzledwhen in a public space. There could also be other rules that limit the ownership of dogs on the muzzled list, like owners having a minimum area of outside space, properly fenced, so that these dogs are not cooped up in flats or in houses with excessively small back yards.
It should be possible to move dogs from the free to muzzled to banned list based on a rolling 5 year review of the number of attacks on human and animals they have made.
I suffered an attack from a muzzled dog, it was on a lead but was too strong for its owner pulled away and left me with a badly bruised arm. I cannot remember the breed or if I really noticed.
Passports not in the drawer I always keep them in. Turning the place upside down.
